This is a 2.2 candidate. However, it needs to be vetted on -current

connecting to a host immediately in the foreground.
I would like to be able to run ppp from a script so that my script can be
sure that it is connected to the 'net before it continues running:
# Dial up the internet.
ppp -background myprovider || exit 1
do-some-net-command
# Hang up the modem.
kill -HUP `cat /var/run/ppp.tun0.pid`
Another problem is that the current ppp calls its process id file
`/var/run/PPP.server', which may conflict if you have more than one IP
tunnel interface available.

Here is also a patch for an improvement: In current imprementation,
even if PPP connection is disconnected by time out, prompt of
interactive mode does not change from "PPP>" to "ppp>" to
indicate the disconnection on a terminal.
So I modified the code to do that. (patch III)

add some logging functionality which I find very useful.
'set debug link' will record just link up/down and address assignments.
'set debug connect' will record the entire chat dialog
'set debug carrier' will record just chat lines including 'CARRIER'
(so that I can be sure I'm getting a 28.8 line).
There was a global change required to permit LogPrintf to take a bit
mask instead of a bit position value (to permit logging some events
on either of two flags, so that no change in 'set debug lcp' would
result from the code supporting 'link'. Thus the diffs are rather
long for such a small change. The man page is also touched.
Oh, and there was a slight syntax problem in route.c

A settable redial timer helps to avoid the problem where both ends
of a link want to dial at the same time and the line winds up busy
for both ends. The process id is logged in /var/run/PPP.system where
system is the name of the called system. When both ends of a link
are running in demand dial mode, you need an easy way to get the pid
of the ppp on the called end so it can be killed and re-started with
-direct or pppd started to handle the incoming ppp session.

6. Just more speak rather silent ignore if you type invalid key words.
The first problem I found was that descriptor 0 was being closed.
This happens because the modem variable is set to 0 to indicate
that it is not valid but there are not enough tests for the modem
variable being 0. You can see where I have done this in the patch.
Code in OpenModem() dups the modem descriptor if it is < 3. Once
this happened the modem was always open and an incomming call would
have getty and ppp reading the modem.
Descriptor 1 is closed when the quit command was executed from a
telnet connection. The next modem open returns descriptor 1
and this gets duped leaving the modem always open again.
The modem was not being closed when the connection dropped or was
closed from the other end. The UUCP lock was also not removed if
the modem could not be opened.
